Retrieving the mechanical key

For a Nissan– and Infiniti-made vehicle, to remove the mechanical key, release the lock knob at the back of the Intelligent Key (remote control or ‘clicker’). Use the mechanical key in the driver’s door key cylinder to unlock the door.

And then in 2017, Infiniti introduced the QX30 and a brand new key fob. At least to them. So, here’s the deal…

The second key fob is the spitting image of the fob used by the Mercedes-Benz folks for years. Old Chrysler Corp. (now FCA) vehicles use it too.

The fob (right) has a tapered tip at one end and a slide lever at the top of the key ring end (1). Slide the lever over and pull the key ring to retrieve the mechanical key.

Nissan GTR, Infiniti QX80 Entry

As noted, the key hole on nearly all Nissan and Infiniti models is visible at the back of the driver’s door handle, and the mechanical key can be used to unlock it. Two exceptions to this are the Nissan GT-R and the Infiniti QX80. The key hole is a bit hidden, behind the front of the driver’s door handle and a cap that must be removed.

To access the key hole, press the rear end of the driver’s door handle to lift up the front end, just as you would normally to get inside. Note the cap shown in the image (above right, A).

While holding the door handle out, use the mechanical key and turn the cap counterclockwise to remove it. Once removed, the key hole is exposed and the mechanical key can at last be used to unlock the driver’s door (above right).

Later QX80, Nissan Leaf Entry

In 2025 and 2026 respectively, the Infiniti QX80 and Nissan Leaf offered a new feature — flush door handles that extend when the key fob approaches the vehicle. If the battery in the fob is weak or dead, this will not occur. Getting to the key hole is a process similar to that for the GT-R. Press the front of the door handle inward. This rotates the rear of the handle outward (right, upper).

The handle can then be pulled open. Do so as far as it will go exposing the key hole beneath the back of the handle (right, lower). You can now use the mechanical key to unlock the car.
